IMPROVEMENT IN WlRE-STRETCHERS.

Specification forming part of Letters Patent No. 196,830, dated November 6, 1877 application filed 7 April 19, 1877.

- Wire-Fence Tighteners, of which the following is a clear, full, and exact description, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a perspective view of my inven-' tion. Fig. 2 is a side elevation. Fig. 3 is a view' of the rear or flat side of the framework.

My invention relates to devices for tightening wire fences; and it consists in the combination and arrangement of devices hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the drawings, A represents a slotted frame having a flat side to lie snugly against the fence-post, and being provided with a pin, a, by which to attach it temporarily to the post While the wire is being placed in position for stretching. This pin may be cast in one piece with the frame A. 1

On the front of the frame are provided the bearings B B for the shaft O, provided with double-cogged cylinder d d, the open drum of the cylinder between the cogs being perforated with a hole, 6, of sufiicient size to receive the end of the wire through it, and thus secure it 'while the drum is being wound up.

On the frame A, and above the bearings B B, I form a recessed shoulder, D, against which fits the double-toothed dog E, one set of teeth, 6', fitting into each set of cogs upon the cylinder, as shown in Fig. 1, thus forming a cheap, convenient, and powerful brace to lock the cylinder, and prevent it from turning back and releasing the strain upon the wire.

The shaft 0 may be operated by a wrench or crank-arm in revolving the cylinder.

I am aware that drums constructed with pawls and ratchet-wheels for tightening wire fences are not new, and I do not claim such to be my invention; but

What I claim as new, and desire to secure by Letters Patent, is--- The slotted frame A, provided with the open bearings B B and recessed shoulder D, in combination with the shaft G, provided with double ratchet d d, and removable" dog E, all constructed to operate substantially as and for the purpose set forth.

CHARLES F. ROTH.
